    Influence of vitamin C on hematololy of Pangasianodon hypophthalmus (Sauvage, 1878) juveniles during pre and post-challenge with Aeromonas hydrophila (Chester, 1901)
    (Society of Fisheries Technologists (India), Cochin, 2018) Daniel, N.; Muralidhar, A.P.; Srivastava, P.P.; Jain, K.K.; Prasad, K.P.; Anandan, R.; Manish, J.
    A 60-day feeding trial was conducted to know the effect of vitamin C on the hematological responses of Pangasianodon hypophthalmus juveniles during pre- and post-challenge conditions with Aeromonas hydrophila. A total of seven purified diets were prepared with 0 (control), 17.5 (T1), 35 (T2), 70 (T3), 175 (T4), 350 (T5) and 700 (T6) mg ascorbic acid (AA) equivalent per kg of diet, supplied as Lascorbyl- 2-polyphosphate (LAPP) and fed to triplicate group of P. hypophthalmus juveniles (mean initial body weight: 3.23±0.01 g to 3.38±0.01 g) for 60 days twice daily. After the feeding and after challenging with A. hydrophila, the haematological parameters were measured in P. hypophthalmus juveniles. All haematological parameter values (except albumin-globulin ratio) viz., serum glucose, total protein, albumin, globulin, hemoglobin (Hb), total erythrocyte count (TEC), total white blood cells count (WBC), hematocrit value (HCT) increased significantly (p<0.05) in treatment groups than control (vitamin C depleted diet). Further, the increased hematological values for most of the parameters were observed in the range of 175 to 350 mg AA kg-1. Therefore, it is suggested that dietary supplementation of 175 to 350 mg AA kg-1 diet would be beneficial for the optimal hematological responses for P. hypophthalmus juveniles

    Nutraceutical and therapeutic applications of squalene
    (Society of Fisheries Technologists (India), Cochin, 2018) Sumi, E.S.; Anandan, R.; Rajesh, R.; Ravishankar, C.N.; Mathew, S.
    Squalene, an isoprenoid molecule present in large quantities in deep sea shark liver oil and in smaller amounts (0.1-0.7%) in palm, wheat-germ, olive and rice bran oils, is well known for its antilipidemic, antioxidant and membrane stabilizing properties. Squalene is a key precursor molecule in the biosynthesis of vitamins, cholesterol and steroid hormones in animals. In human, presence of this highly unsaturated hydrocarbon keeps the skin healthy and protects it from ultraviolet radiations mediated carcinogenesis. Recently, squalene has drawn major attention as high valuable compound due its potential applications in the field of pharmacological, cosmetic, and nutraceutical industries. The present review includes a brief description about the natural sources, properties and applications of squalene.
